如何反序列化具有数组的对象的json？ 使用Newtonsoft xamarin

Question

I am using Xamarin forms and Newtonsoft to deserialize

It doesn't work:

var itens = JsonConvert.DeserializeObject<List<Model.Loja>>(json);

Here is my JSON:

{
  "one": {
    "two": [
      {
        "cod": 142,
        "nome": "name",
        "phone": "23423",
        "endereco": "address",
        "cidade": "city"
      },
      {
        "cod": 142,
        "nome": "name",
        "phone": "23423",
        "endereco": "address",
        "cidade": "city"
      }
    ]
  }
}

Answer 1

Your model needs to match your JSON structure. Try using these classes:

public class RootObject
{
    public One one { get; set; }
}

public class One
{
    public List<Loja> two { get; set; }
}

public class Loja
{
    public int cod { get; set; }
    public string nome { get; set; }
    public string phone { get; set; }
    public string endereco { get; set; }
    public string cidade { get; set; }
}

Then deserialize like this:

List<Loja> items = JsonConvert.DeserializeObject<RootObject>(json).one.two;

Answer 2

You can make a specific model class for that json, try to use http://json2csharp.com/ ,

and then you can parse it using newtonsoft.

If you are using json2chsarp then your specific class will called RootObject, but you can rename it to match your model.

var obj = JsonConvert.DeserializeObject<YourSpecificClass>(json);

Answer 3

The problem was the "[ ]". I used

response = json.Substring(json.IndexOf('['));
response = json.Substring(0, json.LastIndexOf(']') + 1);

And solved it.
